Genes affected

DENR (HGNC:2769): (density regulated re-initiation and release factor) This gene encodes a protein whose expression was found to increase in cultured cells at high density but not during growth arrest. This gene was also shown to have increased expression in cells overexpressing HER-2/neu proto-oncogene. The protein contains an SUI1 domain. In budding yeast, SUI1 is a translation initiation factor that along with eIF-2 and the initiator tRNA-Met, directs the ribosome to the proper translation start site. Proteins similar to SUI have been found in mammals, insects, and plants. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09280321).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.230A>C (p.E77A) alteration is located in exon 5 (coding exon 4) of the DENR gene. This alteration results from a A to C substitution at nucleotide position 230, causing the glutamic acid (E) at amino acid position 77 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
